[0025] Rotating wheels 34 are rotatably installed on both sides of the lower end of the movable support block 32, and a telescopic rod 33 is fixedly installed between the fixed support block 31 and the movable support block 32. The telescopic rod 33 can make the movable support block 32 move linearly when approaching the fixed support block 31.

[0026] The clamping assembly 5 includes a fixing block 51 fixedly installed in the connecting hole 41, a bent metal sheet ring 52 is fixedly installed on the side of the fixing block 51, a connecting block 53 is fixedly installed on one end of the bent metal sheet ring 52, and a spring 54 is fixedly installed between the side wall of the connecting block 53 and the side wall of the fixing block 51.

[0027] The four side walls of the connecting block 53 are all provided with sliding grooves 531, and a clamping block 532 is slidably connected in the sliding grooves 531. A spring 2 533 is fixedly installed between the clamping block 532 and the sliding grooves 531. One side surface of the clamping block 532 is an arc surface. In the natural state, the spring 2 533 can push the clamping block 532 outward.

[0028] The limiting assembly 6 includes a fixing ring 1 61 fixedly mounted on the side of the flange 4 on the gun tail 2, a fixing ring 2 62 fixedly mounted on the side of the fixing ring 1 61, a fixing ring 3 63 fixedly mounted on the side of the fixing ring 2 62, and a fixing groove 631 equidistantly provided on the outer circumference of the fixing ring 3 63, and the clamping block 532 can be slidably connected in the clamping groove 631, and the nozzle and the gun body 1 can be automatically fixed through the clamping groove 631.

[0029] A movable ring 64 is slidably connected to the outer side of the gun tail 2, a bellows 65 is fixedly installed on the side of the movable ring 64, a connecting pipe 1 66 is fixedly installed on one end of the bellows 65, a spring 3 67 is fixedly installed between the inner wall of the bellows 65 and the inner wall of the connecting pipe 1 66, a connecting pipe 2 68 is fixedly installed on the side wall of the movable ring 64, the connecting pipe 2 68 is located inside the connecting pipe 1 66, the connecting pipe 1 66 is slidably connected to the outer periphery of the fixed ring 3 63, the connecting pipe 2 68 is slidably connected to the inner wall of the fixed ring 3 63, and the movable ring 64 can be pushed toward the flange 4 to release the limit between the block 532 and the slot 631.
